YCODMn-1L COD analyzer

Instrument Overview
It is a single parameter measuring instrument developed according to the domestic water quality situation and regulatory requirements, which conforms to the usage habits of domestic users. It is designed and developed according to the GB/T 11892-1989 "Determination of Permanganate Index in Water Quality" standard. Potassium permanganate can be oxidized by potassium permanganate under acidic water bath heating conditions, and the absorbance of potassium permanganate can be measured by spectrophotometry. After calculation by a microcomputer chip, the CODmn value (mg/L) is directly displayed. The instrument is widely used in environmental monitoring, sewage treatment, scientific research institutions, and colleges and universities.
